Height: 6 feet at shoulder
Weight: 2 tonnes
- Adult and juvenile (both sexes): Gray skin covered with coarse, light brown hair.
Preffered Habitat: Forests beside rivers, Swamp.
Diet: Uintatherium’s teeth are small and not well-developed, so it lives on a diet of soft vegetation including leaves, fruit, and water plants
Social Structure: Most adult males are solitary and territorial, only seeking out females during the breeding season. Sub-adult males may congregate in small groups, separating when they reach adulthood. Females are the most social, living together in small to medium-sized herds.
Uintatherium is a large, thick-skinned herbivore which, although unrelated, resembles a rhinoceros and is about the same size as the largest rhino species. Uintatherium carries its barrel-shaped body on column-like legs. It walks only on its toes, and its elephant-like feet are well suited to bearing its weight, although not for running.
Uintatherium is easily recognized for its three pairs of blunt, bony horns on its face, covered with skin and matted hair. The largest horns are situated on the back of the head. These horns vary in size between individuals; however males tend to have larger horns than the females. Uintatherium males also have tusk-like canine teeth on the upper jaw, which fit over bony protrusions (or “flanges”) that protect the tusks from being damaged when the mouth is closed. These tusks are usually either poorly-developed or absent in females.
Uintatherium is an elusive animal which, when it is not eating, spends most of its time wallowing in mud or shallow waters of the many rivers which cut through the Floodplains. It as not as devoted to the water as the hippo-like Estemmenosuchus, and females with young tend to avoid the deeper waters lest the juveniles become Estemmenosuchus' prey. Occassionally, young Uintatherium may fall prey to predators such as Smilodon and Thylacoleo.
Males fight one another over dominance and for females by pushing against one another with their horns, and biting with their tusks.
